To all whom it may com-er Be it known that I, W'iLLLiM'TAr oR, a

citizen of the United States, residing at Minot, in the county of Ward and State of North Dakota, have invented certain new and useful Improvements in Rotary Motors, of which the following is a specification, reference being had therein to the accompanying drawing. This invention relates to rotary motors and more particularly to that class having concentric stationary disks upon which the cylinder revolves.

One object of the invention is the provision of a stationary disk provided with mechanism which is actuated to admit and cut off steam by a plurality of abutments carried by the cylinder whereby the employment of the usual valve gear steam chests, &c., usually met with in motors of this kind are eliminated.

Another object is the provision of a novel form of cutbfi' valve designed to control the intake and exhaust of steam or other fluid.

A further object is the provision of novel mechanism for controlling the operation of the motor whereby the same may be oper-. ated in either a forward or reverse movement.

Other objects and advantages of the in vention will be apparent from the following detailed description when taken in connection with the accompanying drawings.

It will be understood, of course that the essential features of'the invention involved in carrying out the objects of the invention generally stated above, are susceptible to a wide range of details and structural arrangements, but one preferred and practical embodiment thereof is shown in the accom-.

panying drawings, wherein Figure 1 is :an endelevation of the improved motor. Fig. 2 is a front elevation taken on line 22,- Fig. 1. Fig. 3 is a vertical cross-sectional view. plan view. Fig. 5 is a detail perspective Viewv of one of the valves. Fig. 6 is a similar View of the memberattached to the inner face of one of the disks. Fig. 7 is a similar view of one of the abutments. Fig. 8 is a side elevation showing the reversing mechanism. Figs. 9 and 10 are detail sectional views of parts of the reversing mechanism.

'lhe improved motor comprises a rotating cylinder designated by the numeral 5, jourmaled on a pairfof stationary dish 6 andi.

interposed between the opposed faces of the latter-are the rotating valves 8, which are actuated by the abutincnts 9 depending from the inner surface ofthe cylinder The intake ports 10 and exhaust ports 11 formed on and extend 'tiroug'h the dia and are adated to be and closed. through the rotation of valves 8 by the abut-- ments 9, l Y

. The motor may h otherwise rigidly fastened to a she supported by a frame having a bed plate from the opposite ends of which rise'the vertical arms 14 and 15 having on their up ier ends beds 16 12, the latter being held against displacement" by the clamp plates 17 and 18, having concaved inner'faces to mini the outline of the shaft 12, and further provided with perforated lateral cars 19 whi cars 20 on the beds insertible throu h serve to lock the p. tner.

The disks 6 and 7 er held in spaced relation by means of the drum 21, said drum being preferably casting having opposite To bear n similar "king bolts 20 "s of the lugs fiat faces which bear against the opposed faces of the disks suiliciently close to prevent the escape, of steam. The drum. consists essentially oil: a hub-portion from which .v extend the radial arms 23, the latter beingpreferably three in nur'ber and arranged approximately 120 degrees apart. The'te minals of the arms 28 are convexec as shown at 2% and the opposite sides of each arm from the edge of the convex surface 24% to the hub 22 curve inwardly and'outwardly' o the disks 6 and 7 and may beformed of V a single casting or consists, as shown in 3 of a circular rim late 25 from the inner face andopposite edges of which extend the annular cheek plates 26 and 2? which fit 1n annular rabbets formed on the inner races and adjacent the outer edges of the disks 6 and 7. Depending from the rim plate 25 are the abutinents 9, preferably five in numher and approximately seventy-two degrees apart. Said abutments are of a-iength to faces ofthe abutments are flat and bear against the opposed inner faces of the cheap plates 26 and 27, while each of their opposite sides described a compound curve extending from the edge of the concave terminal 28 to the rim plate 25.

The valves 8 are shown to be three in number and are mounted on pivots 29 the ends of which are sunk in the opposed inner face of the disks at points adjacent the inner edge of the rabbet and directly between the ad acent corners of any two of the arms 23.

Each valve is formed similar to the drum 21 and consists of a hub 30, having three radial arms 31. Each arm terminates in an enlarged head 32 having a convex terminal 33 and flat ends 34 and 35. The thickness of the valves is approximately the same as the distance between the opposed inner faces of the disks, and the line joining the inner ends of the fiat ends 35 curves'to the shape of a semi-circle. As shown in Fig. 2, the distance between the remote outer corners of any two of the heads 32 is exactly the same 'as the distance between the adjacent corners of any two of the arms 23 of the member 21, this construction will permit the convex terminal 33 to follow and bear on the recurved surface between any two .arms with sutlicient tightness to prevent the escape of steam. The distance from the pivotal point 30 to the convex surface 33 is substantially the same as the distance from the said pi tal point to the inner surface of the rim plate 25, and the distance between points adjacent the bases of the abutments 9 is substantially the same as the distance between adjacent inner corners of any two heads.

The exhaust ports 11 are preferably three in number and,- disposed intermediate of the pivots 29 and main shaft 12, while the three intake ports 10 alternate with the exhaust ports 11 and are located adjacent the juncture of the disks and cylinder and intermediate of the pivots 30 and one edge of each arm and at an acute angle to said exhaust ports. I

The steam or other fluid for the 0' eration of the described engine or motor is elivered I two openings 42 44 and 45- 46 adapted to be brought to register with the pipes 37 and 48, and 49 and 50 which communicate with said valve casing. The valve 39 may be rotated by means of the hand lever'5l. The

pipes 48 and 49 extend from the valve casing to the engine and each terminates in three branches 5253, the branches 52 being connected with the intake ports 10 and the branches 53 with the exhaust ports 11.

In Figs. 9 and 10 the reversing valve 39 has been shown in detail, and by reference thereto it will be seen that (in Fig. 9) the feed pipe 37 delivers the steam to chamber 40 from which it escapes through pipe 48to the ports 10 of the engine or motor to drive the same forward. In this position of the valve, the exhaust from the engine will be discharged through ports 11 and .pipe 49 to chamber 41 of the valve and discharged therefrom through exhaust pipe 50; In Fig. 10 the valve is shown in its reversing position and by reference thereto it will be observed that steam from the feed pipe 37 enters chamber 41' and is conveyed there to reverse the same. During this reverse operation of .the engine, the steam is exhausted through ports 10, pipe 48, chamber 40 and exhaust pipe 50.

In the operation of the device, itbeing understood that the parts occupy the posithe intake ports 10 and passes between the valves to the abutments 9, during this operation the exhaust ports 11 being sealed or formed between the arms of said valves 8 and also between said valves 8 and the-central member 21 in which the steam expands and impinges against the abutments, forcing the latter to move and-rotate said valves 8 until communication isestablished with ports 11, through which the steam exhausts, while the intake ports are sealed. As soon as the valves 8 uncover the intake ports, communication is cut-01f with the exhaust ports, whereupon steam is admitted to the pockets and its force is exerted upon the abutments 9 to rotate the cylinder. The alternate opening-and closing of the intake and exhaust ports described above is for the forward movement or rotation of the motor. To reverse the same, the reversing valve is rotated to cause the steam to be delivered through the exhaust ports 11 and thereby act upon the opposite s des of the abutments, the ports. 10 in this movementof the motor being the exhaust ports.

The cylinder in this embodiment of the invention has been shown as especially adapted for belt connection with a suitable shaft or the like, but it will of course be understood that the same may be in the form of a gear or the like.
